Abstract

A torque limiting coupling with adjustable intervention threshold comprises: a hollow cylindrical body (2) whose inner walls (2a) are affected by at least two slots (3) which are parallel to the longitudinal axis of the body (2); a solid cylindrical hub (5), which is rotationally retained in said hollow body (2) by means of conventional elements and forms a plurality of radial recesses (7) for the slidingly guided accommodation of corresponding pawls (8) for engaging the slots (3); a presser means (9) for the pawls (18), which is retained in forced contact therewith by means of elastic elements (10) which can be adjusted from outside through corresponding axial openings (4, 6) formed in the hollow body (2) and/or hub (5); the pawls (18) engage, in the torque transmission configuration, the corresponding slots (3) and disengage them, with a centripetal motion into the corresponding recesses (7), in the torque limiting configuration. <IMAGE>
